5. A cougar with a mass of 80 kg is standing at the edge of a cliff. Find the cougar’s potential energy if the cliff is 70 m high.

12m

Explanation:

cuz

The gravitational potential energy: E p = m x g x h where m is the mass and h is the height; m = 50 kg,  g = 9.81 m/s² ,  h = 40 m E p = 50 kg  x 9.81 m/s²  x  40 m

E p = 19,620 J = 19.62 kJ 

odds are decent that your handwriting right now looks a little bit different than it did five years ago, and will look different again in five more. when i look back through my notebooks from middle school to now, i see a long, slow progression from meticulous and teeny letters to bigger, sloppier ones, plus a few side detours: sometime in high school, for example, i decided those loopy cursive lowercase f’s were just the coolest, adopting them as the lone rep for cursive in my otherwise all-print handwriting.
